Abstract
A device that includes an active rectifier () having control gates controllable to produce an output voltage on a DC bus (), a gate control circuit () for producing gate control signals for controlling the active rectifier control gates, a first circuit () connected to the gate control circuit () and producing a command current magnitude signal and a power factor signal for use by the gate control circuit (), a current line () providing a current related to the DC load current to the first circuit (), and a voltage line () providing a voltage related to the DC bus voltage to the first circuit (), the first circuit () including a peak detector () detecting current peaks on the DC bus (), a command current magnitude signal generator () commanding a current as a function of the detected peaks, and a power factor controller () varying the power factor signal () to control the voltage on the DC bus (). Also a method of controlling voltage on a DC bus () based on peak current detected on the bus.
